Standard Filter Housings
Filter Cartridge Housings for the Biopharmaceutical Industry
Introduction
There has been, and is, an increasing demand for quality filter cartridge systems for sterilizing and polishing filtration processes. An emphasis has been placed on the integrity of construction of the filter cartridges. However, the filter cartridge housing is just as an important part of any filtration system. Without a proper housing the cartridge is useless. Even the best filter cartridge cannot do the job if enclosed in a housing that allows fluid to bypass the filter, has external leaks, and is not chemically or mechanically compatible with the application. Quality gas or liquid filtration systems require both quality housings and quality filter cartridges. To meet this need, Sartorius Stedim Biotech has been producing a sanitary line of housings with focusing on quality.
Features
Hygienic, dead space-free design
All product-contact surfaces are electropolished with a surface finish of Ra < 0.5 µm (< 19.6 microinch)
Clamps, flanges and threaded couplings are TÜV-tested (German Association for Technical Inspection and Safety)
Minimal pressure losses thanks to optimized flow patterns
High-grade stainless steel 316 L construction
Options for connecting test and analytical devices
Condensate run-off valves on compressed gas housings
Approved according to Atex EX II 2 G D c
Optimized low hold-up volume design
Ease in Cleaning
Sartorius Stedim Biotech utilizes a unique filter cup design that is conducive to allow a thorough and easy cleaning. The raised filter cup design eliminates small grooves and tight spaces that might be difficult to clean while still permitting free complete drainage of the filter housing.
Flexibility
Sartorius Stedim Biotech offers the widest range of housing sizes and design options to exactly match your flow rate, pressure differential and hold-up volume requirements. Connections are available in many styles and sizes. Custom designs and unique configurations are available upon request.
Ease of Installation
Sartorius Stedim Biotech housings are sold ready to install with all gaskets, o-rings and clamps. The flexible connectivity allows the end-user to install the housings to new or existing hard-piped installations.
Quality of Materials
Only 316L Stainless steel is used for all wetted surfaces to provide maximum durability. Supplied O-rings and gaskets are compounded only from FDA approved materials that meet the requirements for direct contact with food and biopharmaceutical products.
Quality Surface Finishes
All Sartorius Stedim Biotech Sanitary housings come standard with internal finishes of at least 0.5 micron Ra (19.6 microinch) and are electropolished. Electropolishing removes surface impurities in stainless steel left over from the machining and the finishing processes. Such impurities are sites for future initiation of corrosion and possible sources of contaminates leaching into the product. Electropolishing also smoothes the microscratches left by mechanical polishing, thus reducing the total surface area the product will contact, and making it harder for bacteria or contaminates to lodge on the housing surface. Finally, electropolishing leaves a highly corrosion resistant, passive film on the surface of the steel (passivation). Thus electropolishing is the recommended finish for all applications where cleanliness and corrosion resistance are critical.
Quality Control and Documentation
An important feature of pharmaceutical process validation is documentation. All our housings are given stringent inspections during and after manufacturing including dimensional checks, weld inspections, surface measurements and hydrostatic testing. Each housing is labeled by laser with a matching serial number on the bell and base. This serial number provides complete traceability for the Quality Control Certificate, Material Test Reports, and Weld Logs.
PED 97|23|EC Standard
Sartorius Stedim Biotech Stainless Steel Housings are designed and manufactured according the Pressure Equipment Directive PED 97|23|EC. Our manufacturing process follows the highest quality standards and is monitored by an internal quality control system as well as by independent notified bodies on a regular basis.
